' IMPROVE)v sPUns.

TO ALL WHOM IT MAY CONCERN:

Beit known that I, SAMUEL WEHRLY, of San Francisco, county of SanFrancisco, Statie of California, have invented an Improved Spur; and Ido hereby declare the following description and accompanying drawingsare suicient to enable any person skilled in theart or science to whichit most nearly appertains to make and use my said invention andimprovements without further invention or experiment.

The o bject'of my invention is to provide an improved spur for horsemen,and it consists principally in an .improved mechanism for attaching-thespur quickly and firmly to the boot, thus dispensing with the strap orscrews which are used. y

To lmore fully describe my invention, reference is had to theaccompanying drawings, forming a part of this specification, of which-'-Figure 1 is a. side elevation of the spur. vFigure 2 is a sideelevation,showing the` slide. Figure 3 is a. top vfievv.v Figure 4 is a frontview. 4 A Similar letters of reference in each of the gures indicatelike parts'. A A is a curved metal band, which encircles the heel of theboot, and which has the spur-wheel B supported by the arm C at the backof A, as in ordinary spurs. Y

To the sides of the band A, andinear the front extremities, are attachedthe retaining-bolts or serews'a a, beneath which the sliding plate bworks. To the front end of this plate is attached, by a smallprojection, the spring c, which extends back over the plate b. An arm,d, extends upwards fromv this spring, which engages the fixed rackm,attached to the side ofthe hand A. The strap n, is fastened to thesliding plate b5 and passes beneath the boot in from; of the heel.

A curved steel dog, o, is fastened to the inner part of the curved bandA behind, which enters between the top ofthe heel and the counter of theboot. The strap n is then brought closely against the front part of theboot-heel, thus holding'the spur-firmly in place. The spring c forcesthe arm d against the rack m, and holds it wherever desired.

When the spur is to be removed, the spring cis raised hy means of theprojections r r, and the slide allowed to slip forward, thus moving thestrap n, and releasing the dog o.

By. this device,.a neat and substantial spur isobtained, which is freefrom the diiculties of attaching and 'taking off, and, at the same time,is so secu're as to be almost impossible to lose, this making it veryvaluable for cavalry.

Having thus described my invention, what l claim, `and desire to secureby Letters Patent, is-

A spur, having the dog o, the rack m, and arm d, together with thespring c and slotted plate b, the whole constructedand operatingsubstantially as and for the purpose described. I

In witness whereof, I have hereunto set my hand and seal. 4
